  • Flame stabilized oxy-fuel recirculating burner
    Patent number: 4954076
    Abstract: A non-water cooled, nozzle-mixed oxy-fuel burner wherein high oxidant velocity and a venturi aspirate or recycle products of combustion through the burner block and mix them into the flowing oxidant stream to act as a diluent and provide mass to moderate flame temperature. The burner includes means in said oxidant stream to improve flame stability.
